What is the definition of a key fob?
Key fobs are remote control that allows you to unlock and start your car without the need to insert a metal key into the ignition. It's a tiny device with a microchip where information like a unique ID is stored, and an antenna to send and receiving signals. The microchip transmits radio frequencies with the receiver inside your vehicle. These signals are a type of near-field communications (NFC) which allows for contactless payments and other features that require proximity.
Depending on the key fob's model it will have different capabilities. For example, some devices will keep a record of who used the key and when, which can be hugely beneficial in preventing criminal activity. Security measures can also be included, like encrypted keys which make it more difficult to copy. Prox cards are an extremely popular fob type and are sometimes called 125khz prox, 26-bit prox or proximity fobs.
Always have a spare car key fob in case your original is lost or stolen. Some automakers allow you to program a third key fob which can be useful and cost-effective. It is important to note that the process varies between manufacturers and might not be easy. It may be necessary to conduct some research to discover the proper instructions and steps. However, it is worthwhile to have a reliable key fob that can assist you in reaching your destination safely.
